If commitments underlie identity these can only exist as having already been accepted or made and hence in the form of memories of of the singular event in which these were taken up. Such memories are linked to the present by means of the abolition of time in completely experienced memories. But memories are rarely completely experienced, instead they re accessed via pointers or addresses which give them in shorthand, 'thumbnails', belonging to a map of experience in time, and which are therefore not themselves experienceable. These symbolic condensations of past experience are the true private language and their role is fulfilled without any need to re-experience the moments they point to. The complete memories need no longer exist, it hardly matters, and even if one carefully reconstructs an autobiography using them as clues their truth to actualities is immaterial and might just as well be 'secondary revision'. In this way the temporal thickness of the self is reconstructed afresh in each moment. It's not an illusion to be destroyed since that would only bring about fresh illusions, but only disengaged.
